IMPROVEMENT IN C OMBINED BEVELS, SQUARES, AND LEVELS.

Specification forming part of Letters Patent No. 176,870, datedMay 2,1876; application filed April 4, 1876.

To (in whom it may concern:

Be it known that I, SAMUEL W. LLOYD, of Washingtomin the county ofWashington and District of Columbia, have invented certain new anduseful Improvements in Combined Tool; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, which willenable others skilled in the art to which it'pertains to make and usethe same, reference being had to the accompanying drawing, and to theletters of reference marked thereon, which form a part of thisspecifica. tion.

The nature'of my invention consists in the construction and arrangementof a combination instrument for the use of carpenters and others, aswill be hereinafter more fully set forth.

I In the annexed drawing, Figure 1 is a plan View of my invention. Fig.2is a side view, and Fig. 3. an end view, of the same. Figs.

4 and 5 are perspective views of detached parts thereof.

A A represent two parallel bars, which are mortised and securelyfastened into heads or end pieces B B, thus forming the rectangularframe of my combination instrument. The lower ends of the heads B areformed on their inner sides with a horizontal shoulder or offset, a, andtheir outer sides with an 'l -shaped or other suitably-shaped groove.Orepresents a division-block, formed with grooves I2 b in its sides, toslide over the inner edges of the parallel bars A A, and-the lower endof said block is formed with a shoulder or offset, 01, on each side.Through this block is a hole with female screw-threads for the passageof the screw D, one end of which is formed with a tenon, c, to beinserted in a corresponding hole in one of the end pieces or heads B,while a shouldered shank at the other end passes through a box orbearing, G, and said box inserted in the opposite head, and held thereinby tongues and grooves, as shown. On the end of this shank is aremovable handle, H. The division block or nut U is inserted between thebars A A at one end of the frame, where said bars are cut out, as shownat w w, for that purpose. In the grooves on the outer sides of the headsA A are inserted correspondingly-shaped slides I I, which are held atany point desired by means of set-screws hh. The front ends of theseslides are enlarged and curved slightly outward, and upon the same isplaced a rule made intwo parts, J J, hinged together in the center. Thetwo partsof the rule are slotted longitudinally, and held to the ends ofthe slides I I by setscrews on m, passing through said slots into theslides. In the center of one of the side bars A, and in one of the headsB, are inserted spirit-levels L L, which completes the combinationinstrument.

This instrument may be used for a variety of purposes, and it isfastened upon a board, between the division-block G and either one ofthe heads B, by means of the screw 1), which screws up saiddivision-block to clamp it on the board, the shoulders at and a restingon said board, as shown in Fig. 2. The jointed rule J J is thenadjusted, as indicated by dotted lines in Fig. 1, to lay on" a beveledor miter joint at any angle desired from one side, and to lay off fromthe other side the instrument is changed to bring the board on the otherside of the division-block U, and adjusting the rule in the oppositedirection, according to the graduations' thereon.

The instrument can, of course, be used as a rule by fastening the twoparts J J extended on a line, as shown,-and, by, means of thespiritlevels L L, it can be used as a plumb and level. When it isdesired to use it as a square, the rule is moved to one side, and onepart J is turned alongside one of the heads B, and fastened by itsset-screw m, while the other part J is fastened by its setscrew, and

the slide I on that side is moved out to bring the outer edges of thetwo parts J J at right angles with each other, when the two slides arefastened by their set-screws h h. These, slides I are -also graduated,and stationary indexes or pointers p are attached to the sides of theheads B. When, for any purpose, itis necessary to remove thedivision-block G and screw D, said screw is turned so as to move theblock to the points a: on the bars A, when the screw, block, and .box Gcan easily be lifted out.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is-

1. The parallel side bars. A A, grooved and shouldered heads B B,grooved and shouldered division-block (l. tenoned screw D,and box G, allconstructed and combined substantially as and for the purposes hereinset forth.

2. Ihe jointed rule J J, having its parts slotted longitudinally, andadjusted by setscrews m on the slides I I, as and for the purposesherein set forth.

3. The combination of the frame A B, division-block O, screw D, slides II, jointed rule J J, and levels L L, all constructed and arrangedsubstantially as and for the purposes herein set forth. v

In testimony that I claim the foregoing as my own I atfix my signaturein presence of two witnesses.

SAMUEL W. LLOYD.
